GI and GL useless?

[Kärnfysikern]

Found a few interesting things. What do you guys think?

The present results call into question the utility of GI and GL to reflect glycaemic response to food adequately, when used in the context of usual diet

And, adds Richard Mattes, MPH, PhD, RD, a nutrition researcher at Purdue University, "as soon as you put two foods together, it makes the prediction of glycemic index almost impossible," rendering the system practically useless in real-world eating.

One key scientist says that glycemic index "was never intended to be the raison d'etre for eating" and should never be used "in isolation" to construct a healthful diet. That scientist, David Jenkins, MD, PhD, is the man who developed the glycemic index concept back in 1981

cut and paste the link to your browser and remove the spaces after the t and before and after the n to make the link work.

The truth is that the glycemic index is pretty much a moot point as we rarely consume a single type of starch or any other substrate. Mixed meals (with protein, various carbs and fats) result in way different glycemic and insulinogenic responses. Cy or Jared, care to comment?

wow....that is interesting...make you really wonder...i am surprised they didnt think of this earlier...kinda makes sense though...good post man, thanks..

Thans bro.
yeah its always cool to se what the oponets got to say. I have to say though that I will continue to follow GI methods until I se convincing proof that it has no benifits.

[WEBB]

yeah me too...but it is nice to hear about someone challenging the other way....

The GI should never had been taken literally. I think most in here know that. Since you never just eat pure glucose, you won't have a predictable reaction.

I do feel the GI in beneficial however. Your healthier and superior carb choices are almost always have Low GI rating. We all know that stone ground wheat bread is superior to white. Noe if you eat white bread with protein you have lowered your meals total GI. But in terms of health and optimal sources of carbohydrates the wheat is 100x better. That I think is the real benefit of the GI system.

BTW, WTF you been Johan! Good to see you back. I hope school wasn't to rough on ya.

I think that's the main point. The GI levels of higher quality carb sources typically have a lower GI rating.

Interesting read Johan. Glad to see you around.

wow, i had this idea but i think if u have nutritional knowledge, like Giants said, you would have guessed this. in any case, great post Johan... so how was the cave?

I agree with that. Lower gi food are almost always more nutrient dense. But what if you have two foods that are about equal in fiber and micronutrient content but one has say 80 in gi and the other has 60. Now the question is will that make a noticable difference whatsoever over a long time period.
I always pic foods on micronutrient content first. But on other cases I let GI decide.

School was horrible and add the move to it and I was totaly destroyed by stress. But I aced both examns(top of the class acctualy ). I have been relaxing now for a week and a half and getting back on track So you guys will be seeing more of me again now.

Cave??

[Kärnfysikern]

A good example of GI vs nutrient density is something like pasta vs brown rice. The GI is basicly the same, I think pasta has a bit lower GI. So if going by GI the pasta would be the chooise. But brown rice imo is the better chooise because of the fiber and mineral content. I guess the things I pasted say screw gi and go with the brown rice.

Cave??

as in you crawled into a cave for a while. i enjoy reading your posts and it's been a while.

ahh now I understand

Yeah I had to put everything aside and focus on studying
